Description

Die Erfindung betrifft ein Befestigungselement für ein elastisch nachgiebiges Wärmeisoliermaterial, bestehend aus einer Haltescheibe aus Kunststoff mit einer in das Isoliermaterial eindringbaren rohrförmigen Vertiefung und einer durch den Boden der Vertiefung hindurchgreifenden, mit ihrem Kopf anliegenden Schraube, die mit einem Dübel­element zusammenwirkt. Derartige Befestigungselemente werden insbesondere für Dachaufbauten verwendet.The invention relates to a fastening element for an elastically resilient thermal insulation material, consisting of a holding washer made of plastic with a tubular recess which can be penetrated into the insulating material and a screw which engages through the bottom of the recess and engages with its head and which cooperates with a dowel element. Such fasteners are used in particular for roof structures.

Bei einem aus der DE-PS 26 17 911 bekannten Befestigungs­element ist eine Haltescheibe aus Kunststoff vorgesehen, an der zentral eine in das Isoliermaterial eindringbare rohrförmige Vertiefung bzw. ein Ansatz vorgesehen ist. Durch den Boden der Vertiefung ist eine Schraube hindurch­geführt, die innen mit dem Kopf anliegt. Nach Eindringen der Haltescheibe mit ihrer rohrförmigen Vertiefung in die Isolierung wird die Schraube mittels eines Schraubers in den Untergrund zur Befestigung des Elementes eingeschraubt.In a fastening element known from DE-PS 26 17 911, a holding washer made of plastic is provided, on which a tubular recess or an extension which can penetrate into the insulating material is provided centrally. A screw is passed through the bottom of the recess, which rests on the inside with the head. After penetration of the holding disc with its tubular recess in the Insulation, the screw is screwed into the base for fastening the element using a screwdriver.

Für den Fall, daß eine Einschraubung in einen Untergrund nicht möglich ist, also beispielsweise wenn unter dem Isoliermaterial ein Luftzwischenraum vorgesehen ist, ist bereits vorgeschlagen worden, auf dem aus dem Isoliermaterial herausragenden Teil der Schraube einen Klappdübel aufzusetzen, der mit hochgestellten Flügeln durch die Bohrung hindurch­geführt werden kann und danach aufgrund seines Gewichtes oder durch Federdruck aufschwenkt. An den Flügeln sind in bekann­ter Weise Krallelemente vorgesehen, die sich von der Unterseite her am Isoliermaterial festkrallen sollen, so daß beim Anziehen der Schraube eine Verspannung des Befestigungselementes am Isoliermaterial erfolgen kann. Ein derartiges Befestigungsele­ment ist für die Praxis dann jedoch ungeeignet, wenn in senk­rechter Richtung nach unten das Befestigungselement eingesetzt wird. Die nach dem Durchstecken sich selbsttätig aufschwenken­den Flügel des Klappdübels kommen dabei nämlich nicht zur Anlage an der Unterseite des Isoliermateriales, so daß eine Verkrallung und damit auch eine Verspannung nicht möglich ist.In the event that screwing into a subsurface is not possible, for example if an air gap is provided under the insulating material, it has already been proposed to place a hinged dowel on the part of the screw protruding from the insulating material, which has the wings raised through the hole can be passed and then swings open due to its weight or spring pressure. In a known manner, claw elements are provided on the wings, which are intended to cling to the insulating material from the underside, so that when the screw is tightened, the fastening element can be braced on the insulating material. Such a fastener is unsuitable in practice, however, if the fastener is used in a vertical downward direction. The automatically swinging wings of the dowel do not come into contact with the underside of the insulating material, so that clawing and thus tensioning is not possible.

Die Aufgabe der Erfindung besteht darin, ein Befestigungselement der eingangs genannten Art so zu gestalten, daß dessen Einsatz an Wärmeisoliermaterial bzw. entsprechenden Aufbauten in jeder Lage möglich ist.The object of the invention is to design a fastener of the type mentioned in such a way that it can be used on thermal insulation material or corresponding structures in any position.

Gelöst wird die Erfindungsaufgabe mit einem Befestigungselement mit sämtlichen Merkmalen des Anspruches 1.The object of the invention is achieved with a fastening element with all the features of claim 1.

Bei entsprechender Verdrehung der Schraube des Befestigungs­elementes steigt die Gewindehülse auf der Schraubspindel in Richtung des Schraubenkopfes, die zwischen Gewindehülse und rohrförmiger Vertiefung angeformten Stege knicken bzw. beulen sich nach außen aus und kommen zur Anlage an der Unterseite des Unterbaues. Auf diese Weise kann das Befestigungselement den Aufbau verspannen bzw. an einer unter dem Isoliermaterial angeordneten Platte, beispielsweise einem Blech, befestigt werden.With a corresponding rotation of the screw of the fastening element, the threaded sleeve on the screw spindle rises in the direction of the screw head, which is between the threaded sleeve and Tubular recesses formed webs buckle or bulge outwards and come to rest on the underside of the substructure. In this way, the fastening element can brace the structure or be fastened to a plate arranged under the insulating material, for example a sheet metal.

Nach einer bevorzugten Ausführungsart der Erfindung sind die Kunststoffstege am Stirnende der rohrförmigen Vertiefung nach innen abgesetzt angeformt, wobei zweckmäßigerweise in Fort­setzung der rohrförmigen Vertiefung zwei sich gegenüberliegende Stege vorgesehen und die Stege quer zur Achsrichtung profiliert sind, um ein definiertes Ausbeulen bzw. Ausknicken zu erreichen. Die Kunststoffstege haben eine ausreichende Festigkeit bzw. Steifigkeit, so daß in bekannter Weise das Befestigungselement in und durch das Isoliermaterial gedrückt werden kann. Das Befestigungselement setzt mit seinem stirnseitigen Absatz auf einer Unterlage, beispielsweise einem Blech, auf, die angeformten Stege ragen durch eine Bohrung in der Unterlage in den darunter angeordneten freien Raum. Der Durchmesser der Gewindehülse, der die Stege verbindet und der äußeren Abstand der beiden Stege sind zweckmäßigerweise kleiner gewählt als der Außendurchmesser der rohrförmigen Vertiefung.According to a preferred embodiment of the invention, the plastic webs are integrally formed on the front end of the tubular recess, wherein two opposite webs are expediently provided in continuation of the tubular recess and the webs are profiled transversely to the axial direction in order to achieve a defined bulging or buckling. The plastic webs have sufficient strength or rigidity so that the fastening element can be pressed into and through the insulating material in a known manner. The fastening element is placed with its front shoulder on a base, for example a sheet metal, the molded webs protrude through a hole in the base into the free space arranged below. The diameter of the threaded sleeve that connects the webs and the outer distance between the two webs are expediently chosen to be smaller than the outer diameter of the tubular recess.

Ein solches erfindungsgemäßes Befestigungselement läßt sich in jeder Lage an einem Isoliermaterialaufbau, beispielsweise einem entsprechenden Dachaufbau mit Außenfolie, darunter angeordnetem Isoliermaterial und wiederum darunter vorgesehenem Blech einsetzen.Such a fastening element according to the invention can be used in any position on an insulating material structure, for example a corresponding roof structure with an outer film, insulating material arranged underneath and, in turn, sheet metal provided underneath.

The invention is explained in more detail below on the basis of an illustrated exemplary embodiment. Show it:
  • 1 is an enlarged partially sectioned view of a fastener,
  • FIG. 2 shows a further side view of the element in FIG. 1.
  • Fig. 3 shows an installation situation in section through a heat-insulating roof structure after the attachment of the fastener
    and
  • Fig. 4 is a partial view of the situation shown in Fig. 3 during the tightening of the fastener.

Zunächst wird auf die Figuren 1 und 2 Bezug genommen. An einer im Grundriß etwa rechteckigen Haltescheibe 11 aus Kunststoff des mit der Ziffer 1 bezeichneten Befestigungselementes ist mittig nach unten gerichtet eine rohrförmige Vertiefung 12 angeformt. Die Innenbohrung trägt die Ziffer 13. Der Boden dieser Vertiefung 12 ist mit einer durchmesserkleineren Bohrung 15 ausgestattet. Die Bohrung 13 geht mit einer konischen Fläche 14 in die Bohrung 15 über.First, reference is made to FIGS. 1 and 2. A tubular recess 12 is integrally formed on a fixing disk 11, which is approximately rectangular in plan and made of plastic, of the fastening element denoted by the number 1. The inner bore has the number 13. The bottom of this recess 12 is equipped with a smaller diameter bore 15. The bore 13 merges into the bore 15 with a conical surface 14.

In Fortsetzung der rohrförmigen Vertiefung 12 sind nach innen abgesetzt zwei sich gegenüberliegende Stege 17 angeformt, die am anderen Ende durch die Gewindehülse 19 miteinander verbunden sind. Durch die abgesetzte Anformung der Kunststoffstege 17 ist der Absatz 16 außen gebildet. Die Stege 17 sind außen quer zur Achsrichtung mit Verkrallungselementen 18 profiliert.In continuation of the tubular recess 12, two opposing webs 17 are formed on the inside, which are connected to one another at the other end by the threaded sleeve 19. Due to the offset molding of the plastic webs 17, the shoulder 16 is formed on the outside. The webs 17 are profiled on the outside transversely to the axial direction with claw elements 18.

Durch die Bohrung 13 in der rohrförmigen Vertiefung 12 ist von außen die mit einem Schraubendreher zugänglich die mit der Ziffer 2 bezeichnete Schraube eingeführt, die mit ihrem Kopf 21 innen an der konischen Fläche 14 anliegt, mit ihrem Schraubenschaft 22 durch die Bohrung 15 geführt ist und mit ihrem Schaftende in das Innengewinde der Gewindehülse 19 eingreift. Mittels selbstschneidender Schraube kann sich der Schraubenschaft in eine entsprechende Innenfläche einer Kunststoffhülse 19 einschneiden.Through the bore 13 in the tubular recess 12, the screw denoted by the number 2 is inserted from the outside, accessible with a screwdriver, and its head 21 rests against the inside of the conical surface 14 with its screw shaft 22 is guided through the bore 15 and engages with its shaft end in the internal thread of the threaded sleeve 19. The screw shaft can cut into a corresponding inner surface of a plastic sleeve 19 by means of a self-tapping screw.

In Fig. 3 ist dargestellt, in welcher Weise ein solches Befestigungselement entsprechend den Figuren 1 und 2 in einen Isolieraufbau, beispielsweise eines Daches, eingebracht wird. Dazu wird zunächst in den Isolieraufbau eine Bohrung eingebracht, vorzugsweise mit einem etwas geringeren Durchmesser als der Außendurchmesser der rohrförmigen Vertiefung 12 im Bereich der oberen Kunststoffolie 3 und des darunter angeord­neten Isoliermateriales 4. Die rohrförmige Vertiefung 12 setzt mit ihrem Absatz 16 auf dem mit der Ziffer 5 angedeuteten Blechplatte 5 auf. Durch die Bohrung 51 in dieser Blechplatte 5 ragen die Stege 17 mit der endseitigen verbindenden Kunststoff­hülse 19 und der aufgenommenen Schraube 2 hindurch.3 shows the manner in which such a fastening element according to FIGS. 1 and 2 is introduced into an insulating structure, for example a roof. For this purpose, a hole is first made in the insulating structure, preferably with a slightly smaller diameter than the outer diameter of the tubular recess 12 in the region of the upper plastic film 3 and the insulating material 4 arranged underneath. The tubular recess 12 rests on the section 16 with the number 5 indicated sheet metal plate 5. The webs 17 with the plastic sleeve 19 connecting at the end and the screw 2 received protrude through the bore 51 in this sheet metal plate 5.

Erfolgt nun eine entsprechende Verdrehung der Schraube 2 durch Einsatz eines entsprechenden Schraubendrehers am Kopf 21, so steigt die Gewindehülse 19 auf dem Schaft 22 nach oben. Dabei werden die Kunststoffe 17 nach außen ausgebeult bzw. aus­geknickt. Begünstigt wird diese Ausknickung durch die ent­sprechende Profilierung 18 der Stege 17. Die sich ausbeulenden bzw. die ausknickenden Stege 17 legen sich von der Unterseite her an der Blechplatte 5 an, so daß sich das Befestigungselement 1 mit der Halteplatte 11 und den sich nach außen anliegenden Stegen 17 am gesamten Aufbau verspannt. Die Kunststoffolie 3 und das darunter angeordnete Isoliermaterial werden damit an der Blechplatte 5, die mit anderen Befestigungsmitteln an einem Untergrund befestigt ist, gehalten.If the screw 2 is rotated accordingly by using a corresponding screwdriver on the head 21, the threaded sleeve 19 rises on the shaft 22 upwards. The plastics 17 are bulged or buckled outwards. This buckling is favored by the corresponding profiling 18 of the webs 17. The bulging or buckling webs 17 lie against the sheet metal plate 5 from the underside, so that the fastening element 1 with the holding plate 11 and the ones lying against the outside Bridges 17 braced on the entire structure. The plastic film 3 and the insulating material arranged underneath are thus held on the sheet metal plate 5, which is fastened to a substrate with other fastening means.

Es besteht auch die Möglichkeit, die durch die Kunststoff­gewindehülse 19 hindurchgeführte Schraube auf ihrem freien Ende mit einer Mutter oder Gewindehülse zu versehen. Beim Anziehen der Schraube in entsprechende Richtung wird die Mutter oder die Gewindehülse auf den Schraubenkopf zugewegt. Dabei werden die Kunststoffstege 17 der Kunststoffgewinde­hülse 19, die in diesem Falle innen auch ohne Gewinde aus­geführt werden kann, ebenfalls nach außen ausgebeult bezw. ausgeknickt.There is also the possibility of providing the screw passed through the plastic threaded sleeve 19 with a nut or threaded sleeve on its free end. When the screw is tightened in the appropriate direction, the nut or threaded sleeve is moved towards the screw head. The plastic webs 17 of the plastic threaded sleeve 19, which in this case can also be made internally without a thread, are also bulged outwards. buckled.
